AQUA S
DIGITAL PASSIVE INFRARED DETECTOR
aqua_s_en 07/11
The microprocessor-based, fully digital AQUA S detector is characterized by high
sensitivity and interference resistance. A dual pyroelectric sensor is used in the
detector. AQUA S can be supplied with AC or DC 24 V voltage.
The detector is provided with a prealarm feature. Prealarm is signaled by a short
flash of the LED after changes which do not meet the alarm criteria have been
sensed within the detector coverage area. The prealarm sensitivity depends on
what sensitivity is set on the detector pins. Frequently occurring prealarms may
cause an alarm.
For 30 seconds after the power-up, the detector warms up. Only after this time
has elapsed, the detector will be ready to work. Warm-up is indicated by a rapid
LED blinking.

Explanations to Fig. 1:
1 - terminals:
NC – relay (NC)
TMP – tamper contact
24V – supply input (AC/DC)
2 - red LED to indicate:
– prealarm – short flash (approx. 120 ms);
– alarm – ON for 2 seconds;
– warm-up – blinking rapidly;
– low supply voltage – ON.
3 - pyroelectric sensor.
4 - tamper contact.
5 - scale for positioning of pyroelectric sensor against the lens (see Figure 7).
6 - fixing screw hole.
7 - detector configuration pins:
PIR SENS. - setting detector sensitivity (see Fig. 2);
LED ON/OFF - enabling/disabling the LED signaling. The signaling is
enabled when the pins are shorted.

Lenses
An extra wide (EWA) lens is installed in the detector. Optionally, lenses with other
characteristics (coverage patterns) can be purchased and installed.

Installation
1. Open the enclosure as shown on Figure 4.
Fig. 4. Removing the cover.
2. Remove the electronics board.
3. Make suitable openings for screws and cable in the enclosure base.
4. Pass the cable through the prepared opening.
5. Fix the enclosure base to the wall or to the attached bracket.

installation (see Figure 7).

Fig. 7. Effect of the height of installation on the detector coverage area and the
way of positioning the electronics board to optimize the area. Depending on the
mounting height, the medium scale line should be: aligned with the mark on the
enclosure (installation at a height of 2.4 m), situated above the mark (installation
higher than 2.4 m – example B) or below the mark (installation lower than 2.4 m –
example D).
7. Connect the wires to the corresponding terminals.
8. Using jumpers, set the working parameters of the detector.
9. Close the detector enclosure.
Start-up
1. Switch the detector power on. The LED will start blinking (if the JP3 pins are
shorted).
2. When the detector is ready to work (the LED will stop blinking), carry out the
detector range test, i.e. check that movement within the coverage area will
activate the alarm relay and lighting of the LED.
3. If necessary, change the detector sensitivity (pins PIR SENS.).
